What you described definitely sounds more like a bug than a limitation. I’d wait for support, they’ll have to validate the issue by testing it on their end if it’s not already in the log. If they validate it as a new bug then I’d encourage you to document it with this same information in the DNII bugs thread.
I see no reason why the machine should freeze up by design so I can only call it a bug, especially because you can reproduce it every time. The only other thing I might try is see if you can duplicate it in a brand-new project, and if you already have, then I believe you’ve done everything a user can be expected to do, and now you just have to wait on them.
Hope it works out, good thing it’s such a specific issue and not something impairing basic functionality! Good luck!
